For now I can not do it because I have invested my money in promoting this post. If I was a whale then of course I would do it and additionally upvot all participants. Imagine that now I do so without adding 0.1Steem to the pool, the post would be worth 0.02 $ after 4 upvote - to divide. I have a plan to increase the price of the pool proportionally. If at least 4 participants take part in this competition, in the second competition today (I want to publish 2 matches a day) I will add 0.2 Steem, if next 8 people will participate, I will add 0.4Steem tomorrow and so on up to 6.4Steem when there will be 128 people .

This contest is supposed to be a win-win situation for both parties - for me building an account and have a fun, for participants - extra steem + have a fun without the ability to invest excess of time (upvote, comment and resstem take 20 seconds).

Of course, I would be very happy if there was a discussion about the matches under this post because there is not much tennis stuff on steemit.
